Where businesses are in Hamilton
- Hamilton International Technology Park: Business park about two miles from Hamilton and East Kilbride, home to the £110m Lanarkshire campus of the University of the West of Scotland, which says companies on the park can partner with it on research.
- Palace Grounds Retail Park: Retail park in a redeveloped part of the Palace Grounds, visible from the M74, with restaurants and national retailers.
Large employers and sectors with sites here include:
- Local government: South Lanarkshire Council's headquarters is on Almada Street, where its leader, chief executive and the executive directors of all its departments are based.
- Motor retail and coach travel (Park's Motor Group): Park's Motor Group, one of Scotland's largest privately owned motor dealership groups representing 26 manufacturers, is headquartered in Hamilton and also runs Park's of Hamilton coaches.
- Higher education: The University of the West of Scotland's Lanarkshire campus at Hamilton International Technology Park has three buildings, 4,000 students and three academic faculties.
Large, simple roofs on distribution sheds and modern industrial units are usually the quickest and cheapest to fit. Older mill, factory and workshop buildings can work well too, but often need a structural survey first, and roofs from before 2000 may contain asbestos cement: see asbestos roofs.
Grid connection
Hamilton is served by SP Energy Networks (SP Distribution, Central and Southern Scotland). Almost every commercial system needs G99 approval from the network operator before it is switched on, and the question is usually how much the local network can take back. Where export is limited, a G100 export limitation scheme can let a larger array connect. See G99 and DNO applications.
Planning in Hamilton
Planning in Hamilton is decided by South Lanarkshire council under Scotland's own system. Non-domestic rooftop solar is often permitted development under the Scottish rules, but not on listed buildings, in National Scenic Areas or within 3 km of an aerodrome.
Points that come up locally:
- The Chatelherault designed landscape, about 708 hectares on the Inventory of Gardens and Designed Landscapes with the Category A listed Chatelherault building, lies about a mile south east of the town centre, so roofs in its setting may get closer scrutiny.
Our guides on listed buildings and conservation areas explain what these mean for a solar project.
What a business roof in Hamilton could generate
Modelled with PVGIS for the town centre, a south-facing roof at 30 degrees produces about 866 kWh per kWp a year.
| Item | Illustrative figure |
|---|---|
| System | 100 kWp, south facing at 30 degrees |
| Installed cost | £900 per kWp, so £90,000 excluding VAT |
| Generation | About 86,600 kWh a year |
| Used on site | 70% at 24p = £14,549 saved |
| Exported | 30% at 5p = £1,299 earned |
| Total a year | About £15,848 |
| Simple payback | About 5.7 years before tax relief |
Illustrative, not a quote: the same sums as our commercial solar calculator. A company paying corporation tax can usually shorten the payback with capital allowances.
